They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

cabin crew was OK, food was OK, the trip from the US to Munich was actually pretty bad comfort wise. Noisy aircraft, lights never dimmed even in Business class (night flight) barely sufficient amenities for the price. I have millions of miles with United but TBH American is gaining ground and Delta has always been marginally better then United although on paper United has more longes and cheaper upgrades.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Not United Airlines' fault. It's ORL airport's fault.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

I liked the snacks and the flight attendants were friendly.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

Crew in Columbia was not prepared for landing. It was a bit of a disaster and getting bags took forever.

We were upgraded to First Class and it was a great flight

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.

My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

We loved the steward on the plane. He made the night enjoyable

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

It was cancelled at the last moment and the customer services seemed unnoticed to this change and hanged me off the phone the first time I called.

Staff especially Alan Hernandez was a great help with arrangements for my partner and me sit together. This made the trip do much more enjoyable. Thanks so much.

One of the flight was delayed an hour. We then boarded a new flight. We were told to unboard after some other time. To wait for the next flight for another hour. I paid for a short flight that turned in to half a day of travel.

No entertainment, charging, nor wifi on board but I napped for basically the entire time so it was alright. Was allowed to switch seats because the flight was not full but everyone was assigned to the back. Comfortable seats and we got moved to the emergency exit so the extra room was nice.

Painless trip. Only downside: No entertainment system (which we know with Viva & Volaris) and very small seat space. I'm petite and felt squizzed. I'm not sure how most overweight passengers do.

I was charge $90 for my bag more then the fight crazy!! And the plain hit a couple of birds on the take off bird strikes we returned back and had to change planes bad customer service everyone has an attitude problem!!! Bad experience!!!

The bad thing is they didnt send me the deatils about how much alowed bagage ehight 1 carryon or cheacking bag Also they just send in spanishlanfuage i couldnt understand emails

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

They closed the gate over 25 minutes before departure and I didn’t get to board.

No empathy for my situation, arriving at the check-in counter 5 minutes after the deadline to deposit baggage due to a very delayed incoming intercontinental flight. The attendant simply stared past my shoulder and picked up the microphone to announce a "reminder that all passengers must arrive at least one hour before the flight" before speaking to the passenger behind me. I understand that there are rules above deadlines but at least show some damn empathy. It was Christmas morning and I'd been travelling for 20 hours for goodness sake!

Overall a good red eye. Crew chatted very loudly the whole time making it difficult to sleep.

It’s a 2 1/2 hour flight so good and comfort was not my real concern. Safety, easy, fast was what I was looking for. The crews were great, plane was clean, boarding from CBX was fantastic! Definitely traveling this way again.

The money you save flying volaris is not worth it

Is was a good short flight with some turbulence! I would fly Volaris again.

We had boarding passes for the next flight but we could not catch the flight in the small airport just because volaris closed the boarding at the counters an hour before for which we had to sepnd almost 3+ hours to catch next flight. There are hardly anyone who can speak english, but thank God, we have found an young man who could not only speak English but helped us book for the next flight. The air crafts are noisy and scary sometimes to hear that squeeking noises during the take off and during the flight. They do not even offer a cup of coffee for free in flight. The prices are super high and the services are zero. That’s pretty much for this airlines in summary.

Unfortunately it was not a good flight got canceled had to be at the airport all night long to get a different flight to another airport my first flight with Volaris was very bad. Poor services

The boarding , and it would be nice if they would let us know head of time about flight changes

The fly was 2 hours delayed and the plane was old and dirty. A very umcorfotable flight, which I won't recomend to anyone

The flight was delayed by two hours. I had paid for extended leg room. Due to the delay, the plane was different and I didn't end up having extended leg room. I finally was able to reach Volaris on Whats App and they gave me an airline credit. I wanted a refund to the credit card since I hardly ever fly Volaris. Other than that, it was a very comfortable flight.

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

Plane and crew on board were fine. Everything else was terrible.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.
